SAFE OR VAULT PROTECTION.

SPECIFICATION forming part of Letters Patent No. 642,684, dated February 6, 1900.

Application filed November 26, 1898. Serial No. 697,508. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES EYSTER, a citizen of the United States, residing at I-Iolcomb, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in Safe or Vault Protection, of which the following is a specification.

The object of this invention is to protect a safe or Vault by an outer casing, the combination-knob and bolt-throwing levers of the casing-door operating the connection-knob and bolt-throwing lever of the safe or vaultdoor.

In the accompanying drawings, Figure 1 is an isometrical representation of a safe and outer casing and a mechanism for operating the combination and bolts. Fig. 2 is avertical section through the doors of the casing and safe. Fig. 3 is a vertical section through the doors of the casing and safe and the levers for operating the bolts. Fig. 4 is aface representation of the inner end of the lever after operating the bolts of the casing-door, showing the lever of the safe-door.

The outer casing is composed of the front 1, ends 2, top 3, and bottom 4, made up of metallic plates secured together in any suitable manner. The front has an opening 5, closed by a hinged door 6. This hinged door supports a combination-knob 7 and a lever 8 for throwing the bolts 9. The shank 10 of the combination-knob 7 extends through the door and supports a sleeve 11, having a hollow center 12 and radial flanges 13. A latch 14 has a pivotal connection with the flanges 13,which guide it in its movement. A plunger 15 is located in the sleeve and guided by the projection 16, moving in the groove 17, and a spring 18 holds the plunger in its outward position in a yielding manner. The latch is of such form that when the plunger is in its outward position the inner end of the latch will be depressed and when the plunger is in its innermost position the outer end of the latch will be depressed, as shown at Fig. 2.

The lever 8 for throwing the bolt-works of the outer casing extends through the outer door, and to its projecting end is secured an extension having a slotted end 19 and depend ing socket composed of the end 20 and sides 21 and 22. The side 22 is shorter than the side 21. A cam 23 projects from the extension.

To the inner face of the door of the outer casing is pivoted a bail or loop 24, resting upon the cam 23.

Within the casing is located a safe 25, havin g a door 26 and the usual combination-knob 27 andbolt-throwing lever 28. The combination-knob has a lengthwise groove 29. At the front corners of the safe are located channelbars 30, embracing the front and sides of the safe. These channel-bars are secured to the top and bottom of the outer casing in any suitable manner. A-top channel-iron bar 31 embraces the front and top faces of the safe and is secured to the upright channel-bars 30. Rods 32 connect the upright channel-bar with the bars 33, extending across the rear of the safe. The front face of the upright channelbars are provided with hooked projections 34: and 35, facing each other. A bar 36, having its ends reduced to fit within the hooked proj ections 35, is placed across the safe-door and held within the hooked projections by the cams 37, pivoted to the upright channel-bars 30. Opposite the bolt-throwing lever of the safe and from the bar 36 rises a projection 38, curved in form, and to the upper face of this bar is securely fastened a spring-bar 39.

When the door of the outer casing is opened and the safe-door unlocked, the parts will appear as shown at Fig. 1, and upon the removal of the bar 36 the safedoor can be opened. I

In securing the doors the safe-door is closed, the bar 36 placed across it, and the cams turned down over its ends. If the dials of both combination-knobs correspond,the outer end of the latch will enter the slot 29 of the knob of the safe-door, and the lever for throwing the bolts of the safe-door will be received within the depending socket of the extension securedto the bolt-throwinglever of the outer door, and as the door to the outer casing is closed the knob of the combination of the safe-door will force in the plunger 15, which will be raised by the cam 23 into engagement with the hooked projections 84, and by turning the knob 7 the combination of the safedoor is thrown off, thereby locking the bolts. The lever 28 in turning to throw the bolts will depress the spring 39, as shown at Fig. 4E, so that the longer side 210i the socket will pass the end of the spring. Should the safe be forced back from the upright channel-bars $30 and the bolt-throwing lever be freed of its engagement with the socket, the spring 39 will move in contact with the side 21 of the socket, thereby holding the bolts of the door of the outer casing thrown, also holding the bail in connection with the hooked projections 34, so that the outer door will be locked after the influence of the combination controlled by the knob 27 has been withdrawn, and it will be necessary to force an entrance through the outer casing in order to restore the safe to its former position. The beveled end 2L0 of the rear wall 90 ot' the extension will engage the upturned portion 38, thereby drawing the door of the outer casing firmly into position, and the rear wall. 20 will engage the upturned portion 38 and tend to form a connection between the door of the outer casing and the upright channel-bar.

In the latest make of safe and vanlt doors, when the bolt-works are withdrawn the-combination-knob remains stationary, and in closing the door of the outer casing, should the outer end of the latch fail to enter the groove of the knob 27, the latch will bear against the conical end of the knob, and by turning the knob controlling the latch the latch may be turned until it will enter the groove, when the door may be closed, which will force in the plunger and force the outer end of the latch farther into the groove.

So far as known to me I am the first to form a connection between the combinationknobs so that both combinations can be manipulated in unison, also to form a connection between two sets of bolt-works, so that both will be operated together.

I have not shown all the mechanism for throwing the bolts and operating thecombination, as such parts are old and-form no part of my invention.

It will be noticed that it is not necessary to form any permanent connection with the safe-door in the way of attachments, which will be appreciated by the owner of the safe.

In the drawings I have shown the rear of the safe unprotected by the outer casing, as such rear wall may be a part of the building, or the casing may extend around it.

I claim as my invention- 1. In a safe or vault protection, an outer door and an inner door, each provided with a dial and knob, and a movable lever, the combination-lock of the inner door controlling the movements of both levers.

2. In a safe or vault protection, an outer door and a movable inner door each provided 4:. In a safe or vault protection, an outer door and an inner door, each provided with a dial and knob, the spindle of the knob of the outer door supporting a projection and the knob of the inner door having a peripheral lengthwise groove adapted to receive the projection.

9. In a safe or vault protection, an outer door, and an inner door, each provided with a bolt-throwing lever and adapted to be 0perated in unison, and other securing means for the outer door operated by the movement of its bolt-throwing lever.

10. In a safe or vault protection, an outer door, and an inner door, each provided with bolt-throwing levers and adapted to be operated in unison, a bar extending across the face of the inner door, the lever of the outer door having an engagement with the bar.

11. In a safe or vault protection, an outer door and an inner door, each provided with a bolt-throwing lever and adapted to be operated in unison, and a removable bar extending across the face of the inner door, the lever of the outer door having an engagement with the bar.
